Additional LAN interfaces are provided in the OAM card for connecting main and subtended chassis. In case of TJ1600-6 chassis, the NMS1 and NMS2 ports of HCPOAM03 card in main chassis can be connected to other subtended chassis using two RJ-45 cables. The subtended chassis can connect to other subtended chassis thus supporting a linear or ring form of multi shelf arrangement.
Follow the procedure for connecting the main and the subtended chassis in TJ1600-6:
1. Identify and label the cables.
2. On main chassis, connect one end of the cable to RJ-45 connector on NMS1 port of HCPOAM03 card and the other end of the cable to either NMS1/NMS2 port (RJ-45 connector) of first subtended chassis.
3. Similarly, connect a cable to RJ-45 connector on NMS2 port of HCPOAM03 card on Main chassis and the other end of the cable to either NMS1/NMS2 port (RJ-45 connector) of second subtended chassis.
4. Route the NMS cables through the cable routers securely along the left side or right side of the rack.
5. The two subtended chassis connected to main can be connected to other slave chassis using the unused NMS1/NMS2 port of connected subtended chassis.
Following figure shows the multi shelf connection between main and subtended.

NOTE: For TJ1600-11, MGN1 and MGN2 interfaces are available on HCPOAM01 card for multi-shelf connectivity. For TJ1600-2, P1 and P4 interfaces are available on OAMC card for multi-shelf connectivity.
17.2 Configure subtended shelf from SLAT page
Subtended shelf is configurable from SLAT page when the multi shelf option is enabled on the main shelf configuration.
Ensure the LAN cable is physically connected between main and subtended shelf.
Perform the following steps to configure the subtended shelf:
1. Pre-configure the Slave shelf Id is in the main shelf UI. For more details, refer to TJ1600 Product Family User Interface Guide.
2. On Configure Slat Node page, select the Mode as Subtended Shelf from the drop down.
3. Enter the subtended shelf id same as pre-configured from main shelf UI.
